To all whom it may concern:

Be it 'known that I, JAMns ELLIS HALE, a citizen of the United States, residing at Akron, .in the county of Summit and State of'Ohiofhave invented new and useful Improvenients in Vehicle WheeLRims, of which suitable means for securely mounting the I ,/The invention contemplates the tire-carrying rim on the vehicle wheel rim in such a manner that it may be readily removed and replaced when desired to enable the 'user oft-he vehicle to substitute a tirerim carrying a fresh tire at any time without the requirement of especial tools or any unnecessary delay by substituting for therim carrying an old tire, a rim carrying a' fresh tire.

. provision 1 of a pair-of split contractible bands adapted split rings laterall to be mounted on the vehicle wheel rim and provided with, inclined. side faces, around which is mounted the wheel carrying rim havingagroove in its inner surface provided with inclined portions to engage the inclined portions ofsaid split rings. The arrangement is such that when the split rings are shifted laterally away from each other the inclined ortions of the rings en gage the'inclined aces .of'the tire-carrying rim with a wedging action for securely holding the latter against movement. The means which I prefer to employ'for shifting the away. from'each other consists of aplura ity of threaded elements extending through suitable-apertures in the wheel-rim havin outwardly-projecting coniwpally-shaped en s to engage suitably inclined portions offthetwegrmgs for forcing them apart. With the foregoing and other objects-in; view, the i ention-consists in the novel construction, co 'binationLand-arrangement of parts constituting the7'invention to believeinafter specifically described and illustrated in thef-acctgmpanyin'g drawing which forms Specification vof Letters Patent.-

a part hereof wherein is shown the preferred embodiment of the invention but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto 'appended. v a

i The drawing presented is a transverse sectional View of the rimlportion of a vehicle wheel showing portions of. the mechanism for supporting the tirercarryingrim in section.

Referring to the drawings in reference numeral 1 indicates the rim of a vehicle wheel supported by spokes 2. The outer face of the rim 1 is preferably flat and is further provided with a plurality .of spaced threaded apertures'3 arranged in a series, extending circumferentia-lly around the rim. Mounted in these apertures are screws 4 provided with outwardly-extending conically-sha-ped ends 5, and these screws are locked against rotation by means of lock or jam-nuts 6. Mounted on the outer face of the rim 1 are a pair of splitrings 7 having the lateral opposing faces 8 thereof'inclined as shown to form an annular recess arranged to receive the conical heads 5 of the rings 7 is an annular endless tire-carrying 'rim 11, usually, although not necessarily, provided with flanges 12 and provided in its inner face with a groove 13 the lateral walls 14 of which are inclined with an inclination approximately equivalent to the inclination of. the sidewalls 9 of the ring 7 so that the rim inclosesand seats on the inclined faces 9 of the rings 7. p

In assembling a wheel for use embodying this invention the screws 4 are withdrawn sufficiently to leave the outer face of the rim 1 unobstructed, after which the rings 7 are seated in the groove 13 of the rim 11 and then shifted laterally, .to place after which the screws are manipulated to cause 7 their conical heads 5 to move outwardly into the annular recess formed between theop- .;posing faces 8 of the rings 7, indoingjthis detail the face or the rim 1. The removal ofthe rim 11 is effected by reversing the foregoing operation.

It will be pointed out that the employ,

ment of the elements 4, having conical heads 5 engaging the opposing walls 8 of the rings 7 also serves tov support the central portion of the rim 11, which is highly desirable where a tire having a hard rubber base is used which is liable to be fractured by any movement such as bending or flexing of the rim, in which the tire is seated.

I claim:

1. The combination with a vehicle wheelrim provided with a series of radial openings arranged circumferentially of said rim, a pair of split expansible rings mounted on said rim, the outer lateral faces of which are inclined and with their opposing faces out-- wardly converging to provide a circumferentially-extending frusto conically shaped recess between them, radially movable means mounted in the openings in said rim and projecting into said recess for forcing said rings laterally away from each other, and a tire-carrying rim provided in its inner face with a shallow frusto-co-nically-formed groove adapted to be mounted on said rings and to be held securely on said rim when said rings are laterally forced away from each other to bring their inclined portions into engagement with the inclined edges of the groove in said tire-carrying rim.

2. The combination with a vehicle wheel rim of a pair of. l-aterally-shiftable split expansible rings mounted thereon and spaced from each other to provide between them a circumferentially-extending recess, radiallymovable wedging means carried by said rim and adapted to project into said recess for forcing said rings laterally away from each other, an endless tire-carrying rim inclosing said rings and provided in its inner face with inclined portions complementary to the lateral -faces of said rings and adapted to be engaged thereby when the latter are forced apart to lock said tire-carrying rim detachably in place and simultaneously contract said rings on the outer face of said wheel-rim.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JAMES ELLIS HALE.
